            Abstract:
            The development and verification of memorized type natural gamma spectralog instrument are introduced. In order to improve the parameters acquisition capability of throughpipe memorized logging system and meet the requirements of measurement accuracy of shale gas well geological interpretation, based on the analysis of the working principle, software process and ground algorithm of existing natural gamma ray spectrum instrument, combined with the technological characteristics of the throughpipe memorized logging, the memorized type natural gamma spectralog instrument was developed by using sophisiticated hardware circuit and the acquisition software, the automatic stable spectrum technology, the spectrum processing technology of least squares inverse matrix algorithm and the data integration processing technology of the double detectors. The preliminary verification shows that the consistency and stability of the instrument is good.
